养殖和自然生境:中国潮间带底栖纤毛虫多样性和群落结构的对比研究
Aquaculture and natural habitats:Comparison of diversity and community structure of benthic ciliates in China's intertidal zones
摘要
Abstract
In recent years,continuous coastal development has led to large-scale conversion of natural mudflats to aquaculture mudflats in intertidal zones,resulting in the loss of benthic biodiversity and alterations in community structure.However,systematic understanding of the differences in benthic biodiversity and community structure between aquaculture and natural mudflats,as well as their driving mechanisms-particularly large-scale spatial drivers-remains limited.This study focused on benthic ciliate communities in China's intertidal aquaculture and natural mudflats.Using one-way analysis of variance(ANOVA),linear regression(LR),distance-based redundancy analysis(dbRDA),and variation partitioning analysis(VPA),we examined the differences in three dimensions of α-diversity(taxonomic,functional,and phylogenetic diversity)and community structure(species composition and functional composition)of benthic ciliates between the two types of mudflat,along with their driving factors.The results revealed that:① no significant differences exist in local environmental variables between the two regions,indicating that aquaculture activities did not significantly modify habitat physicochemical conditions;② significant differences existed in α-diversity,species composition,and functional composition of benthic ciliates between aquaculture and natural mudflats;③ mean annual temperature(MAT)emerged as the primary driver of the observed differences in ciliate α-diversity and community structure.The results of this study demonstrate that large-scale climatic variables,rather than aquaculture impacts,are the key drivers of divergent patterns in benthic ciliate diversity and community structure between the two mudflat types.These findings provide critical insights for balancing intertidal mudflat aquaculture development with biodiversity conservation.关键词
